Transmitter and receiver magnetic rotors are provided wherein each of the rotors comprises a plurality of magnets. Each magnet has a magnetization direction which lies normal to the axis of rotation, and at least some magnetization directions are non-parallel with other magnets' magnetization directions. The magnetization direction of a magnet may be at an offset angle relative to adjacent magnets. The transmitter and receiver may be symmetry about a bisecting plane, and the receiver's magnetization directions may correspond to a rotation of the transmitter's magnetizations directions about an axis parallel to the transmitter's axis of rotation. The magnets in the transmitter and receiver are oriented to reduce rotor vibration due to magnetic coupling between the rotors.
